Portable Noise Reduction Shed

ABSTRACT

A noise reduction shed formed by two or four L-Shape foldable panels, with full walls on the left, right and back side and with no wall or partial wall on the front side. Each L-Shape foldable panels includes two basic panels, a group of folding brackets, latches and folding handles and can be folded for storage and unfolded for forming the shed. Each L-Shape foldable panels include two basic panels and each basic panel consist of multiple layers of sound absorbing, sound isolation, sound damping materials and a cover to maximize the noise reduction purpose. The noise reduction shed is used to house the generators or other high noise equipment inside to reduce the noise to the outside.

Background

The present disclosure relates generally to a portable noise reductionshed that are formed by two or four L-Shape foldable panels, with fullwalls on three side and a full or partial open on the fourth side, tohouse generators or other high noise equipment inside to reduce thenoise level of equipment to the outside environment.

Current ways of reducing the generator or other noisy equipment noiselevel are either building a noise reduction enclosures as part of thegenerator or the equipment itself, or building a separate enclosure withfull walls, ceiling and floor to fully enclose the generators or othernoisy equipment inside . Since these enclosures are fully enclosed withfull walls on all sides, so they have to include electric fans andventilating louvers on the wall to let the fresh air in, exhausted airand heat out during operation. Main problem with these full enclosuresis once the fans stop working while equipment inside is still running,the enclosure will be overheating and causes safety issues.

Thus, there exists a need for a more innovative product that can reducethe noise level but at the same time doesn't require the fans andelectric power when housing the generators and other noisy equipment init for noise reduction.

Examples of references relevant to existing enclosure for noisereduction include U.S. Patent References: U.S. Pat. Nos. 9,641,043 and4,871,922. The complete disclosures of the above patents and patentapplications are herein incorporated by reference for all purposes.

SUMMARY

The present disclosure is directed to a portable noise reduction shedformed by multiple L-Shape foldable panels to house generators, or othernoisy equipment in it to reduce the environmental noise level duringoperation. This portable noise reduction shed includes two or fourL-Shape foldable panels to form into different size of inside space tohouse different size the generators or other noisy equipment. Theportable noise reduction shed formed by the L-Shape panels has full wallon three sides and a full or partial open wall on the fourth side.

When all L-Shape foldable L panels are unfolded and coupled to eachother, the portable noise reduction shed is formed and ready to housethe generator or other noisy equipment inside . When all L-Shapedfoldable panels are disconnected and folded, the portable noisereduction shed is in storage condition. Each L-Shape foldable panelconsists of two basic panels that are coupled by folding brackets. Eachbasic panel is constructed with multi layers of sound absorbing, soundinsulation, sound damping materials and a cover to become a completesound transmission barrier.

Compared to current fully closed enclosures that house the generators orother noisy equipment to reduce the noise, the portable noise reductionshed in discussion reduces the noise level greatly on three sides thathave the full wall and the top that has the full ceiling, it does notrequire the electric fans, ventilating louvers and electric power sincethe exhausted air and heat get out of the shed from the fully orpartially open front wall, thus greatly reduces the risk of theoverheating during equipment operation inside the shed.

The readershould understand that a given feature need not be the same or similarto the specific portrayal of a related feature in any given figure orexample.

Referring to FIG. 1, an overall view of a portable noise reduction shedformed by two L-Shape foldable panels is illustrated. As shown in thisillustration, the first L-Shape foldable panel 100 forms a left wall anda top ceiling, the second L-Shape panel 200 forms a right wall and backwall. While these full walls on the left, right and back, as well as theceiling on the top, consist of multi layers of sound absorption, soundinsulation and sound damping materials in them to act as sound barrierso the noise level outside these full walls and ceiling are greatlyreduced, the portable noise reduction shed has its front wall open,allowing the exhaust air and heat inside to go out when generator orother noisy equipment are placed inside for noise reduction duringoperation.

Referring to FIG. 2, an overall view of the L-Shape foldable panel 100and 200 in unfolded position is illustrated. As shown in thisillustration, each L-Shape foldable panel 100 and 200 includes two basicpanel 101, two folding bracket 103, several latches 102 and foldinghandle 104. The two basic panel 101 in the L-Shape portable panel 100act as the left wall and top ceiling of the portable noise reductionshed, the two basic panel 101 in the L-Shape portable panel 200 acts asthe right and back wall of the portable noise reduction shed. Theportable noise reduction shed is constructed when putting the L-Shapefoldable panel 100 on top of L-Shape foldable panel 200 and locked toeach other by the latch 102. The two folding brackets 103 that coupledthe two standard basic panel 101 together in both L-Shape foldable panel100 and 200 are in unfolded position and lock the two basic panel 101into a perpendicular position.

Referring to FIG. 3, an overall view of the L-Shape foldable panels 100and 200 in folded position is illustrated. The L-Shape foldable panel100 and 200 can be folded to flat shape for storage when the portablenoise reduction shed is dismantled and the L-Shape foldable panel 100and 200 are separated. The two basic panel 101 are parallel to eachother when the L-Shape foldable panel 100 and 200 are in the foldedstorage position.

Referring to FIG. 4, the shape of two basic panel 101 and basic panel110 (basic panel 110 will be referred later) is illustrated. Both basicpanels 101 and 110 have the same shape and structure but different sizeand both have the mounting holes around the edge and center. Thesemounting holes are for bolts to go through to connect the basic panel101 and 110 to the latch 102, folding bracket 103 and handle 104accordingly. When two basic panel 101 are coupled together by thefolding bracket 103, they form into the L-shape foldable panel 100 and200. When one of each basic panel 101 and 110 are coupled together bythe folding bracket 103, they form into a L-Shape foldable panel 300(L-Shape foldable panel 300 will be referred later).

Referring to FIG. 5, the structure of the basic panel 101 and 110 isillustrated. Each basic panel 101 and 110 consists of four layers faceto face to each other. The first layer is a cover 105 which acts as thesupporting structure for other layers to be attached to. The secondlayer 106 is made from sound damping material. The third layer 107 ismade from sound insulation material and the fourth layer 108 is madefrom sound absorption material. These four layers are both glued andbolted together as a sound barrier to either block or absorb the soundcoming from the generators or other high noisy equipment inside theportable noise reduction shed and thus the noise outside the back, left,right and top of the noise reduction shed are greatly reduced. At thesame time, the heat and exhausted gas generated from the generators orother high noisy equipment inside the noise reduction shed arecirculated out of the portable noise reduction shed through its frontopen wall.

While the noise reduction shed can be formed by two L-Shape foldablepanels as described above, it can also be constructed by four L-Shapeportable panels with doubled inside space as illustrated below.

Referring to FIG. 6, a portable noise reduction shed formed by fourL-Shape foldable panels is illustrated. These four L-Shape foldablepanels include two L-Shape foldable panel 100 and two L-Shape foldablepanel 300.

Referring to FIG. 7, the layout of the four L-Shape foldable panels toform the portable noise reduction shed is illustrated. As shown in FIG.7, the two L-Shape foldable panel 100 are paired side by side to eachother by latch 102 and act as the back wall and top ceiling of theportable noise reduction shed. The L-Shape foldable panel 300 has thesame composition as L-Shape foldable panel 100 except it consists of onebasic panel 101 and one basic panel 110, instead of two basic panel 101.The two L-Shape foldable panel 300 are paired together tail by tail bythe latch 102 to construct into a C shape panel and this C shape panelacts as the full left wall, full right wall and partial front wall ofthe the portable noise reduction shed. The noise reduction shed isformed when laying the paired L-Shape panel 100 on top of the pairedL-Shape panel 300. As shown in FIG. 6, the noise reduction shedconstructed by two L-Shape foldable panels 100 and two L-Shape foldablepanels 300 has full wall on left, right and back, but only has thepartial wall on the front top, with most portion of the front wall open.

The noise reduction sheds constructed by either two or four L-Shapefoldable panel can be portable, or they can be also stationary whentheir walls are anchored to the ground foundation as described below.

Referring to FIG. 7, several L-Shape anchor bracket 109 are used toanchor the portable noise reduction shed to the ground. This is achievedby first attaching the vertical surface of the L-Shape anchor bracket109 to the left, right or back wall of the portable noise reductionshed, then anchoring the horizontal surface of the L-Shape anchorbracket 109 to the ground.
